Nowadays traditional Chinese qigong is no longer exclusive(独享的) to the elderly. Lately, a video of Baduanjin got popular on the Internet. 1.
Baduanjin has a history of over 800 years. It was created during the Song Dynasty. As the name shows, Baduanjin is made up of eight groups of movements. 2. So it used to be seen as a sport for the elderly.
In recent years, however, many young people came to realize the beauty of the sport. Baduanjin is easy to learn and requires no tools and little space. So it's perfect for office workers, because they often feel a pain in their necks and shoulders. 3. There is also a book named Baduanjin Exercise for children to do exercise.
“I’ve been doing Baduanjin for a month and it makes me sleep better. I think Baduanjin is really helpful,” a young man said. 4.
But according to the scientists, not all people are suitable for practising Baduanjin, and patients who may fall easily shouldn’t do the exercise. 5.

1. A
2. E
3. C
4. D
5. B

我们可以根据上下文逻辑逐一匹配选项：
1. 空前句提到八段锦的视频在网络走红，A选项“并且八段锦成为了年轻人的新宠”顺承网络走红的结果，衔接自然。
2. 空后句提到“所以它过去被看作是老年人的运动”，E选项“和球类等其他运动相比，八段锦动作缓慢柔和”是它过去被认为是老年运动的原因，逻辑通顺。
3. 空前句提到上班族经常肩颈疼痛，C选项“那是因为长时间坐着”正好解释上班族肩颈疼痛的原因，衔接合理。
4. 空前句是一位年轻人分享自己练习八段锦的好处，D选项“除了他之外，很多人都表示八段锦能帮他们放松”顺承个人的例子，扩展到更多人的反馈，符合语境。
5. 空前句提到不是所有人都适合练习八段锦，容易摔倒的患者不能做这项运动，B选项“我们必须始终把安全放在第一位”是对前文注意事项的总结收尾，逻辑通顺。
多余选项为F。
